Patent ES-244660-A1 (ES)
Title: Improvements in or relating to the manufacture of anhydrous aluminium chloride
IPC: C01F7/58
Filed: 1958-10-14
Abstract: A continuous process for the production of high-purity aluminium chloride comprises continously passing chlorine into the foot of a vertical reaction vessel packed with a bed consisting of separate lumps of aluminium metal, continuously introducing lumps of aluminium into the top of the vessel so that impure aluminium chloride vapour formed towards the foot of the vessel is purified by fractionation as it rises through the bed, continuously removing the purified vapour from above the bed and condensing it within, but out of contact with the walls of, a separate chamber, the whole process being effected with exclusion of water vapour. The upper region of the reaction vessel may be externally cooled. The reaction may be initiated by preheating the lower region to 400 DEG C.-600 DEG C., the remainder of the vessel being maintained at nearly 200 DEG C. The aluminium may be supported on a grating such that ashes and impurities may collect below the grating and be periodically removed. Any molten aluminium will collect underneath the grating and react with incoming chlorine, thereby providing in part an automatic temperature control. Specification 678,563 is referred to.

Abstract: In Example 5 a violet foil is obtained by mixing polyvinyl chloride with dioctyl phthalate and gelatinizing the mixture while adding linear quinacridone <FORM:0900757/IV(a)/1> which has been ground in a ball mill with acetone. If in addition to the quinacridone, titanium dioxide is added, a pastel red foil is obtained.ALSO:Crude linear quinacridone pigments are conditioned by grinding with at least one part by weight of an organic solvent per part by weight of pigment in the absence of an inorganic salt, until the pigment has the desired state of fineness and the solvent is then removed to an extent such that the pigment is obtained in a pulverulent form. Solvents specified are benzene, toluene, chlorobenzene, trichlorobenzenes, nitrobenzene, carbon tetrachloride, methanol, ethanol, isopropanol, butanols, amyl alcohols, acetone, methyl ethyl ketone, diacetyl alcohol, tetrahydrofurane, dioxane, morpholine, pyridine, piperidine, diethylamine, dimethyl formamide, formic acid and acetic acid. Dispersing agents and texture-improving agents may be present during the grinding. The quinacridones used may be substituted by nitro groups, alkyl, e.g. methyl groups or halogen atoms. Examples are given.

Title: Pin receptacle and carrier member therefor
IPC: B21D51/10
Filed: 1969-07-14
Abstract: An electrical socket comprises a contact spring assembly 7 enclosed by a sleeve 12, which are formed from portions 1, 3 of a metal blank B. The portion 3 has spring contact forming strips 10 and is rolled to form the contact spring assembly 7 with a pin receiving mouth 11. Assembly 7 is doubled over at neck 2 to lie with mouth 11 along edge 4A of the portion 1, which is then rolled about assembly 7 to form the sleeve 12. The sleeve may be tapered to fit tightly over part 2A of neck 2. The portion 1 may be dimensioned such that a partly doublewalled sleeve is provided, Figs. 6, 7 (not shown), this preventing ingress of solder and also providing a greater resilience to the sleeve. The contact springs may be offset axially to lessen the pin insertion force required, or may be helically formed, Figs. 10, 11 (not shown). An electrical connector assembly, Fig. 8, has rows of holes 20 in the insulating carrier 15, through which the sockets are pushed. Modular electrical unit 25 with pins 24 is inserted into, and held by, the resilient sockets. This combined unit may be mounted on a printed circuit Fig. 9 (not shown) with the sockets being dip soldered to the respective conductors of the printed circuit through which they project.

Patent ES-429934-A1 (ES)
Title: Air brake antiskid control
IPC: B60T8/46
Filed: 1974-09-10
Abstract: An antiskid control valve for use with an air brake system on a vehicle which also includes an antiskid control system capable of detecting actual or potential locking of the braked wheels and providing a signal to actuate the antiskid valve. The antiskid valve provides for unrestricted operation of the brakes by delivery of air from a reservoir to brake actuating chambers until a signal is received of a potential wheel lock at which time the brakes are automatically released and further delivery of air from the reservoir to the brake chambers is prevented until the braked wheels resume rotational speed. After the wheel lock condition is avoided, the brakes are reapplied at a controlled rate due to a restriction in the line delivering air from the reservoir to the chambers for operation of the brakes.

Patent ES-445776-A1 (ES)
Title: Methods and apparatus for separating glass sheets into separate sheet portions
IPC: C03B33/03
Filed: 1976-03-04
Abstract: For separating glass sheets, especially sheets of wired glass, into separate sheet portions and stacking the sheet portions in spaced stacks, the sheets are cut to define the sheet portions, which are gripped by respective relatively movable groups of suction gripping devices. The cutting may be effected by scoring the glass sheet before it is gripped by the suction devices, and then snapping it either before or after gripping it with the suction devices. The sheets may be lifted from a roller delivery conveyor into engagement with the suction gripping devices by a series of transverse lifting tines. The groups of suction gripping devices are then moved apart to separate the cut sheet portions, and in the case of wired glass this also severs the wires. The suction gripping devices are mounted on a carriage so that, while still held by the suction gripping devices, the separated sheet portions can be transported laterally to a stacking station, at which they are released to drop on to respective stacks of similar sheet portions on a stacking table. A transfer carriage with lifting arms is provided to transfer the stacks to the pivoted arms of a tilt table for swinging the stacks into a vertical position ready for subsequent removal.
